According to a 2009 ILSI (International Life Science Institute) report, the main prerequisites involved in tooth decay development are tooth, dental plaque and substrate. Dental plaque results from the colonization of the teeth surface by oral bacteria from saliva. These bacteria are then able to form a biofilm on the tooth that is reinforced by bacterial product, salivary proteins and food substances from the diet.    Maltitol and Xylitol Sweetened Chewing-Gums Some bacterial species can become predominant in the tooth colonization and among them, some produce acids inducing the dissolution of tooth mineral. Saliva could be considered as a primary defence mechanism against bacterial infection in the oral cavity. It clears bacteria from the mouth by aggregation and flushing and by buffering and counteracting bacterial acid production in the oral ecosystem. Read more>>>>>>>>>>

The introduction of adhesive systems for orthodontic bonding has dramatically decreased a time consuming step in fixed appliance therapy. Since the introduction of the adhesive technology by Buonocore in 1955 and the first report of its use in bracket placement by Newman  in 1964, there have been considerable developments in all areas. Enamel etching was first performedwith 80% phosphoric acid but soon changed to a 37% solution, which was routinely accepted by the end of the last millennium. Subsequently the introduction of self-etching primers has again brought a dramatic change in etching technology.  Not only were new etching agents such as polyacrylic acid and maleic acid introduced, but the etchant was combined with the low viscosity composite matrix which potentially enhanced the penetration of the etching relief. Alongside the etchants, adhesives have also evolved. Whereas initially Newman  advocated the use of an epoxy resin, polyacrylic resins filled with...
